Hi AVG team,
I have a link (https://mail.eafreemail.com) which I trust and some PC shows a pop up that threat is detected.
I am looking for the way to require whitelist this matter but I couldn't find in AVG. Could you please let me know what is going on and how to resolve it?
Looking forward to your reply.
Thanks
